parden my bad english,im from Norway

Accubonds are longer than conventional bullets and may restrict powder capacity of your cases. You may end up with a 2600 FPS load. Is that enough to allow the bullet to perform as intended at the range you will be shooting? I’m assuming you want to be able to take longer shots.

i was thinking of using the accubonds out to 400maximum for moose,im not shure how the 285 eld m's perform at closer ranges on moose,i assume they might be a bit to soft? especially if you hit a shoulder bone?
